Update Switcher.tsx

[yuting1214]

It looks like the problem resulting from the developers were trying to integrate the components from "lucide-react" into their self-created components.

The props for "ThemeSwitcher" did not support "size" as argument comparing to the interface from "lucide-react"

import { Camera } from 'lucide-react';

// Usage
const App = () => {
  return <Camera color="red" size={48} />;
};

export default App;

That's why I slightly update the parent component(ThemeSwitcher), instead of children components like (EmptyChat and Navnar).

Hope this would help.(I've tested it.
